S.D. Codified Laws § 27B-7-51.1

Any person involuntarily committed shall be discharged if the director of the South Dakota Developmental Center or the director of a developmental disability community service provider determines that the person no longer meets commitment criteria. The South Dakota Developmental Center or community service provider shall immediately notify the chair of the county review board who issued the commitment order that the person no longer meets commitment criteria and that the person is being discharged. Nothing in this section precludes any person or the person's legal representative from subsequently seeking admission to a program on a voluntary basis.
